"Two reviews: the sports bra is the most comfortable I have worn!! As an avid runner I am looking for something that will provide enough support but not suffocate me. Also, the customer service was exceptional. My package got lost and they sent me a new one right away. I will definitely be ordering more colors soon."
"Love the fit and color of this sports bra. I wear between a small and a medium and the medium fit perfectly. My only complaint is that the racer back strap is a little high on the back of my neck. It’s still very comfortable but I prefer it to hit a little lower. Overall- excellent!"
"I’ve been slowly changing out my workout clothes to brands made without forever chemicals. That’s how I found Definite Articles. I love them! The shorts are soft and stay put. This sports bra is my favorite. It’s also soft and breathable. I live in Hawaii and train in the heat and humidity so breathability is a big deal. I’m so glad I found this brand. I’m going to order two more of this product right now!"
"Great bra, feels like I have nothing on and I like that it's free of chemicals. I'm very small chested and the XS fits perfect and doesn't totally flatten me out like other sports bras I've tried"
"I am overjoyed with the bra, biker shorts and racer back t shirt I recently purchased and put to the test in the 100 degree hot room. Comfortable, great fitting, moisture wicking and non- toxic is all I can ask for. I will be purchasing more ASAP!"
"I have a relatively slim frame and a large bust and I have never liked many sports bras. I was SO excited to find something that is not only clean materials, but also actually provides great support for high intensity workouts and is comfortable enough to spend the whole day in without giving the uni-boob look. I highly recommend this bra!"
"Because of their environmental commitment the materials are nice with a strong band underneath the ladies but I’m afraid the headlights are on under a normal shirt. And the straps need to be shorter for me (5’1 and petite)"
"Can't wait for more colors in these tops!! For is great! Stay in place during hot yoga. . full coverage. . . some other brands are too low and when you bend down its easy for the tops to also go down. . . not the look you want. . . . these stay in place and the material is great Regarding size. . . since wear a large the size is a bit loose in chest. . . but nothing that gaps. . ."
"Love this sportsbra! I love the idea of wearing workout clothes that are good for you and it fits great and does it's job perfectly."
"I really like the fabric and how the bra is cut because it does not rub my armpits or against my scapulas."
